scan.c File Reference

Detailed Description

Example application to demonstrate using the MMWLAN scan subsystem.

Note

It is assumed that you have followed the steps in the Getting Started guide and are therefore familiar with how to build, flash, and monitor an application using the MM-IoT-SDK framework.

This example application provides a very basic demonstration of the MMWLAN scan API. It simply initiates a scan (with default arguments) and displays all results. Note that the MMWLAN scan implementation does not sort or cache scan results. As such, it is possible that a single Access Point may appear multiple times in the results displayed by this example application.
